SHINGLE REMOVER Filed Aug. 29, 1929 INVENTOR 10 BY [90 Zebmm j}? 5 J3ATTOR/Y'EY Patented Jan. 12, 1932 PATENT OFFICE LEO LEHMAN, OF POMEROY,WASHINGTON SHINGLE REMOVED,

Application filed August 29, 1929. Serial No. 389,145

This invention relates to shingle removers 4' and has as one of itsobjects to provide a tool adapted to remove shingles in their logical.and in their reverse order in which they were laid.

Another object of the invention is to provide a shingle remover that byremoving the upper course first will deposit all dirt and removedshingles to the ground over the unremoved shingles.

A further object of the invention is to provide a shingle remover .thatwill operate between the sheathing boards and without interference fromthe rafters thereby providing for greater rapidity inthe work, the workbeing thus unobstructed by the remaining standing shingle nails.

' A further object of the invention is to provide a shingle remover thatis relatively light in weight and that is provided with adetachablehandle for convenience in storage 1 and shipping.

A further obj ect of the invention is to prob vide a shingle removerthat by its design is especially adapted to start the work with thegreatest ease and rapidity.

A further object of the invention is to pro- I vide a shingle removerthat by operating between the sheathingboards will act as a safeerenceis now had to the accompanying drawingsin which Fig. 1 is a sideelevation of a fragment of a roof;

Fig. 2 is an end elevation thereof showing the position of the devicewith respect to the roof- Fig. 8 is an enlarged side elevation of theshingle remover showing one position of the device during operation;

Fig. 4: isa plan view of the device showing its relative size withrespect to the space between the sheathing boards and the rafter andFig. 5 is a similar view to that of Fig. 3 showing another postion ofthe device durin operation.

illaving reference to the drawings like numerals refer to like partsthroughout the several views and the numeral 1 refers to a shingled roofcomposed of shingles 2, laid in the usual manner on sheathing boards 3,which sheathing boards are in turn supported by rafters 4, the differentcomponents being assembled in the usual manner of such construction,with th eaves 5 of the roof repre senting the lowermost part of theroof, and the comb 6 representing the uppermost part 7 thereof.

It is the general practice in such roof construction to save lumber bylaying the sheathing boards 3 about 2 inches apart, and as the lumber is1 inch stock (nominal dimension) there remains a space approximately 1inch between the rafters 4 and the underside of the shingles 2 by 2inches between the sheathing boards, and this space is taken advantageof as will be noted as the specification proceeds.

The shingle remover 7 forming the subject matter of this inventionconsists generally of a bayonet shaped tool 8 having a handle 9,elongated as shown for two hand operation, which is detachably attachedthereto for the purpose of removal for convenient storage or shipping,and specifically the tool consists of an elongated blade 10 sharpenedpreferably to and terminating in a point 13, the sharpened point beingshaped to force an entrance under the shingles under all conditions thatmay be encountered, more particularly when starting the work, and thepoint is further preferably tapered from both edges of the blade, asshown in Fig. 4, whereby to glance away from the nails that hold theshingles when it is necessary to pass the blade between the sheathingboard and the shingles, by which taper no appreciable interference willbe encountered which would be the case were a blunt or broad tool used.

Formed integral with the blade 10, and extended at approximately rightangles thereto, is the riser 14 which meets the blade with a curve 15,the curved portion being formed in the riser with the blade forming atangent thereto. the curve shown in Figs. 3 and 5 is relatively large itis thus shown to illustrate the action of the tool, since in practicethe curve will be smaller whereby with the power applied to force theblade under the shingles the smaller curve will tend to break theshingles quicker (rather than bending them as shown) resulting inexpediting the work.

The tool 8 is completed with a shank 16 which is also preferably anintegral part of the tool, and the shank normally extends in a lineparalleling the line of the blade, and is disposed to receive the handlewhich is secured thereto'preferably by means of U bolts 17, or othersimple means which willpermit of its ready removal, which handle isintended for convenient and proper manipulation of the tool.

The tool is constructed of a comparatively narrow thin, flat strip,0fyielding or resilient material, preferably of uniform cross i the toolis determined by the nature of'the material used, and is such asptoprovide the necessary resiliency, i. e. to yield under heavsectionthroughout its length, and its blade dimensions are such as to permitits entrance in the space bounded by the shingles and rafters and thetwo adjacent sheathing boards of greater width than the thickness of thesheathing boards. 4

The thickness dimension of the material of ier work as where theshingles are exceptionally well secured, and to remainrigid under thelighter work. i

By its resiliency the tool under the heavier work will assume theposition (exaggerated) shown in Fig. 5 when forced under the shinglepreparatory to lifting them wherein it will be noted that the curvature15 of the riser 14; is greater than shown in Fig. 3, (also exaggerated)and by thus increasing the curvature the wedge or lifting effect isgreater, due to I the yielding qualities which permit the change and bymeans of the sharpenedpoint 13 of of curvature.

In use the work is started by providing a hole that will permit theentrance of the tool at the comb of the roof, or obviously the roof maybebroken into at a valley (not shown),

the blade.

The hole being started its size is increased until the blade may beoperated with a swinging movementunder the shingles 2, passing over therafter l whenthat member is in the vicinity of the actual operation, andthe motion of swinging brings the curved portion 15 of the riser incontact simultaneously with the underside edge of the shingles.

This operation starts lifting the shingles as the blade proceeds alongtheir underside, and simultaneously finishes raising the Let it here beunderstood that while" shingles, which are now loosened, by contact withthe curved portion of the riser the resiliency of the tool preventingjar to the handle during the operation.

This last part of the operation (obviously in cooperation with the firstpart) provides a lifting effect which'bends the shingles upward 'totheirbreaking point when the natural resiliency of the shingle, augmented bytheresiliency of the tool, causes the shingle to break and fall overonto the unremoved shingles.

The sharpened point 13 permits driving the tool between the shingles andthe sheathing without considering the location of nails, or wheneverstubborn resistance is encountered. 7

Obviously there is no dirt between the sheathing boards, instead alldirt lays between the superimposed shingles; hence, operating from thecomb of the roof down, the removed shingles will be thrown over onto theunremoved shingles, and will carry with them practically alldirt, withthe result that the dirt and old shingles are prevented from fallinginto the building, and are swept or fall by gravity to the ground. Thisobviously 'diii'ers from the effect of-working from the eaves'upward asin this case all dirt and much of the shingles would eventually land inthe interior-of the building.

Having thus described my invention, I claim:

1. A shingle remover consisting'of a re: silient tool formed bayonetshaped of a narrow thin flat strip, and provided with a bination of aresilient tool of uniform cross section throughout its length, andformed of a narrow thin flat strip of yielding material having a greaterwidth than the thickness of the sheathing boards which carry theshingles, and having general dimensions adapted to permit its entrancebetween shingles, between the shingles and the supporting rafters, andbetween the edges of adjacent sheathing boards, and provided with a twohand handle detachably attached thereto, and comprising an elongatedblade terminating in a sharpened point, ta-

pered from both edges of the blade, a riser formed integral with andleaving said blade with a curve, and a shank formed integral 3. Ashingle remover consisting in com;

with said riser and normally extending in a. line paralleling the lineof the blade, and adapted to receive said handle, said riser beingdisposed with respect to the blade and shank to cooperate with saidmembers to yi'eldingly engage underside and the edge of said shinglessimultaneously and without jar to the handle during operation.

In testimony whereof I afiix my signature.

LEO LEHMAN.
